[Tutor] sftp using subprocess

[Asad]

Hi All,

        I get the following error :

>>> sftp_process = subprocess.Popen(['sftp', '-b', 'batch.txt', user_host],
shell=False)
>>>

Permission denied (keyboard-interactive,publickey,password).
Connection closed

Is there any other way to acheive this because I cannot import pexcept
module .

Thanks,
